Abstract: PURPOSE:To detect the abnormality in the operation of a head carriage of a printer. CONSTITUTION:Sensors 208 and 216 are set on the moving route of a head carriage 205 to sense when the head carriage 205 passes. Before the printer starts operating, the head carriage 205 is moved, and the position of the head carriage 205 when the sensors 208 and 216 respond is stored as the number of pulses from a home position.
